Deon Ludick,

NHS Mechanical Engineering, BSc Hons Applied Sciences

Deon Joined AESPUMP as a reliability Specialist in 2015 focusing mainly on assessments on the condition and performance of pumps to identify poor operating conditions to customers, and assisting the customer with Root Cause Failure Analyses investigations. He obtained a National Higher certificate in Mechanical Engineering at Wits Technikon in 1982, and furthered his studies in 2002 to achieve a BSc Hons in Applied Sciences at the University of Pretoria in 2003. Deon started his career as a Mechanical Technician at Eskom’s Engineering Investigations Division in 1982, conducting acceptance and performance tests on various mechanical equipment.

In 1989 he joined Sasol, a Petrochemical Company, in the mechanical maintenance department covering all aspects of asset management, project management and shut down management. Finally he was appointed as a specialist to focus on equipment reliability.
In order to have adequate information to address the root cause of problems, he developed two systems to capture operational deviations:

  • From DCS captured data, alerts were set up to capture information when equipment was operated beyond allowable or design parameters. Actions were also taken to address the consequences of deviations experienced.
  • Information from daily plant inspections (gauge pressures, temperatures, flows, vibration etc.) were captured with bar codes and scanners. This enabled effective trend monitoring and fingerprinting of equipment. Once again alerts were triggered when allowable or design parameters were exceeded.

Information generated from these two systems shortened Root Cause Analyses investigations considerably and clear distinction could be made between operational or equipment problems. A MTBF increase from 20 months to 70 months was achieved at the plant where these two systems were implemented.

Glenn G Clayton, QBE

Glenn started his career in Operations in 1971 and worked his way up to the level of Senior Process Technician (control room operator) with AECI Umbogintwini and Modderfontein a major chemical and explosives manufacturer in South Africa. In 1975 he left Operations to go into mechanical engineering as a Fitter Machinist where he underwent an apprenticeship with SAPREF (Shell & BP) a major refinery in South Africa. He qualified by doing a voluntary trade test 2½ years later. He stayed on after qualifying, concentrating on the overhaul of critical equipment, steam turbines and compressors. In 1981 he started his own business specialising in the maintenance of turbines and compressors and critical rotating equipment.

In 1983 he re-joined Shell in its Chemical Division on an Alkylation plant as a supervisor where he worked himself up to Mechanical Maintenance Superintendent and subordinate competent person for the site.
In 1988 he left to try his hand at sales where he worked as a mechanical seal representative for John Crane until 1995 at which time he was promoted to Branch Manager, Durban. He remained in this position until 2000 when he was promoted to Oil & Gas and Paper and Pulp Market Sector Manager for Sub Saharan Africa.

In 2001 he was fundamental in starting up and was the General Manager of a Rotating Equipment reliability based subsidiary of John Crane called Performance Plus and combined the management experience and technical expertise to deliver optimum solutions for improved plant performance and availability at reduced operating costs. The core competence of this company was to maximise the performance of the existing processes, to achieve increased production at reduced operating cost, adding significant value to the assets and extending field life whilst at the same time optimising supply chain management. Glenn ran this business for 7 years and has an intimate knowledge of the systems, processes and reliability tools used, like Interface Reliability Software, MTBF Charting, Fat Analysis as well as other reliability diagnostic software developed in South Africa under his instruction, namely analytical versions of Pareto Analysis, Bad Actor Analysis and Footprint Analysis.

Over 7,000 pumps and associated systems were under continuous improvement initiatives in Sasol Synfuels in Secunda, Sasol Industries in Sasolburg, Natref Refinery in Sasolburg, Engen Refinery in Durban, and CABGOC a Chevron Upstream facility in Malongo, Angola where he was fundamental in realising an average of 400% reliability improvement over all of the South African companies.

In 2004, Glenn was promoted to Director at John Crane South Africa. From 2006 he also headed up the Project Division of John Crane SA, building up the project department until they were the supplier of choice in industry. During this time he also successfully project managed the LOPC Project on John Crane’s behalf, which was an environmental project, upgrading dual seals and systems to over 200 pieces of rotating equipment at SAPREF refinery in South Africa.

He has also been instrumental in improving reliability and process optimisation within the mining industry, specialising on tailings and HPAL autoclaves and associated equipment. Some of the groups associated in this field were DMSA

Madagascar, a division of Sherritt International, Sumitomo Corporation and Korea Resources Corporation, Rossing Uranium, a division of Rio Tinto in Namibia, Langer Heinrich Uranium, a division of Paladin Energy Ltd in Namibia, Kansanshi Copper Mine in Zambia, a division of First Quantum Minerals, the Anglo-American Group in South Africa and Black Rock Mine, a division of Assmang Manganese.

Glenn is an experienced Engineering Manager with a demonstrated history of working in the mechanical and operational engineering industry, skilled in Oil & Gas Upstream and Downstream Processing, Chemical Processing, Mining, Reliability Engineering, Root Cause Analysis, Rotating Equipment, Autoclaves, and Mechanical Seals and Seal Support Systems.

Rob Adam

Rob has been involved in the Mechanical Seal Industry for the past 40 years, where he started his longstanding career as an apprentice at Sapref (Shell and BP). During this time, Rob was fortunate to enter the Sapref bursary program through the Natal Technical College, and gained his T3 National Diploma, and became a qualified Artisan. Rob was appointed as Design Draftsman at EPC and soon after moved to National Trading where he then spent 10 years as a successful Sales Manager for the Chesterton SA distributorship, furthering his skills and knowledge in this industry.

Rob then went on opening his own business, Confluid, which after 10 years was bought out by AESSEAL.Rob has been appointed as the Sales Director of AESSEAL since 1999 and is highly competent across all wet mechanical sealing and gland packing applications, and an expert in Autoclave Sealing.
